B4

Nucleus -  Contains DNA which contains the instructions for making proteins/enzymes

Cytoplasm  -   Gel-like substance where proteins like enzymes are made for respiration and       photosynthesis

Cell Membrane  -  Holds the cell together and controls what goes in and out. Lets water pass   freely but blocks chemicals

Mitochondria -  Where enzymes needed for AEROBIC RESPIRATION are found and where the reaction takes place

Cell Wall -  Supports and strengthens the cell. Made of cellulose.

Vacuole - Contains cell sap, (the liquid content of a cell) , made from a weak solution of sugar     and salt

Chloroplasts  - Where the reaction for PHOTOSYNTHESIS takes place (contains chlorophyll and the enzymes needed for this reaction)

PLANT AND ANIMAL CELL ONLY:

Nucleus, Cytoplasm, Cell Membrane, Mitochondria, Cell Wall, Vacuole, Chloroplasts

Yeast Cells are used to make bread and wine

Bacteria Cells dont have:

• A nucleus, they have a ciruclar molecule of DNA instead
• A mitochondria, but they can still respire aerobically
